To all whom, it may concern: which bears against the tape D, so as to press Be it known that we, SAMUEL WV. EVANS, the latter against the th reads B, and also hold Jr., EDMUND L. GLENN, and lVILLIAM H. GAS- said tape while the pellets or fulminates are KILL, citizens of the United States, residing engaged by the striking-linger G, which is in the city and county of Philadelphia, State preferably formed of wire and radiating from 55 of Pennsylvania, have invented a new and the top of the reservoir A, it being seen lthat useful Improvement in Pocket-Lamps, which said wire is coiled through an eye H on the improvement is fully set forth in the followreservoir, thus providing a spring for the iiningspeciication and accompanyingdrawings. ger, and also connected with an eye Il', also xo Our invention consists of novel features in on the reservoir, whereby said finger is prop- 6o a lamp employing a strip of fulminates for erly held in position.

Rising from charge of the same. To accomplish this the 5o and secured to the pocket E is a spring F, lower edge of the threaded portion B ot' the Ioo reservoir has a recess l), into which the fulminates successively enter, and are thus removed from the path of the sharp edge of the bottom coil of the threaded portion, the upper wall ot said coil, however, being in position to ride properly under the fulminates, and thus raise the saine with the strip. As there is lateral pressure on the tape or fulminates, owing to the rotation of the portion I3 of the reservoir, and a consequent tendency of said tape to displacement, the sides of the spring are formed with guides G, which project inwardly from said spring, so as to enter the pocket E and embrace the sides of the tape.

R designates the cap of the lamp, the same being shown closed in Fig. l2 and open in Fig. l, and being hinged to the outer casing E', the side opposite to the hinge having a snap or catch S for holding the cover in closed position. The hinge of the cap, Fig. 12, consists of a staple-shaped piece T of wire, which is mounted in the ear U on said cap, and having its legs entering ears V on the side of the casing and soldered or otherwise fastened thereto.

The reservoir A may be supplied with oil at the bottom thereof through the opening occupied by the plug.

In Fig. 13 we show a portion ot a beaded rim employed in lieu of the milled rim, Figs. 1 and 4.

The casin g E', pocket E, ear V for the hinge ot the cap, and the eye W, which receives the lower end of the spring F, are formed in one piece of metal suitably drawn, as will be seen in Fig. ll.

The bushing l and plug L have their threads formed by rolling or spinning, said bushing and plug being constructed of sheet metal.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. In a pocket-lamp, a casing with a rotatable reservoir therein, having a removable cap with a wick-tube, eyes H Il. and the screwthreads B, said tube, eyes, and threads being stamped or struck up and integral with said reservoir, a strip of fnlminates, a finger for holding said strip of fuhninates relatively to the screw-threads of the reservoir, and a strikiin g-iin ger, said parts being combined substantially as described.

2. A lamp having a strip of fnhninates, in combination with a striking-finger, which is connected with the top of the lamp and provided with a coil around the attaching-eye on said top, substantially as described.

3. A casing having a pocket with a strip of 'fulminates therein, in combination with a rotatable lamp, and a stationary bushing interposed between said casing and lamp, substantially as described.

4t. A lamp having a reservoir with a removable top portion provided with a Wick-tube and the eyes li li', a wire passing through said eyes and forming a striking-linger, and a strip of fulminates adapted to be brought into contact with said finger, said parts being combined substantially as described.

5. A lamp consisting ot' a reservoir with wick-tube J and threaded portion l), and provided at its lower end with a threaded bushing, a threaded plug in said bushing and having a projecting rim, an outer casing with vertical pocket, a bushing between the reservoir and casing and closely fitted to said easin g, a

l strip ot fulminates in said pocket, a strikingfinger secured to the top ot the reservoir, and a spring bearing against said strip, said parts being combined substantially as described.

G. A lamp consisting of a rotatable reservoir having a threaded portion with recess I.) in its lower edge, with a striking-finger sccured in ears on the top thereof, an outer casing with vertical pocket, a strip of fulminatos in said pocket, and a spring secured to said casing adjacent to the pocket therein, being projected upward to form a bearing against said strip and having side projections forming guards for said strip, said parts being combined substantially as described.
